I’m super interested in this space! Agree with sibling that focus here is on knowledge management while question mentions media, which is probably even more interesting challenge. I recently dreamed up something that kinda resembled Airtable (which you should check out), albeit I was thinking more of datomic like system as opposed to tables (more flexible, but tables are nice and simple). I like the mention of wiki like system, I still find wikipedia to be my favorite knowledge source. I guess for me the ideal system has bunch of requirement you haven’t mentioned:

- mobile and desktop friendly (especially input) - full local backup, including any metadata (so that I can always use another software, not cloud-first-with-export) - can be purely single-person (plenty existing sharing platforms) - it’s gotta support arbitrary nesting (I hate evernote/one note three levels to a wisiwig page rigidness) - any others?

I also wonder whether there’s enough market for selling this software (Airtable is going after business use cases, the single-player use case makes it quite limited).
